This invention relates to improvementsin atomizers and has particular reference to a perfume atomizer. z An ,object of the invention is to provide an improvedqatomizerbgf*simple, practical f and compact construction, which may be carried about the person or in a pocket-book, and from which the contents will not leak while the'device is not in aise.

Therabovel and other objects will appear more clearly from the following detailed de scription, when taken in connection with the accompanying drawing, which illustrates a preferred embodiment of the inventive idea. In the drawingv r Figure 1 is a side elevation of the atomizer constructed in accordance with the invention;

Figure 2 is a top plan view; Figure 3 is a vertical longitudinal section 2o onthe line 3 3 lof Figure 2; and

Figure 4 is anenlarged fragmentary sectional view through the atomizing chamber. The atomizer of the present inventionis particularly designed as a pocket devicev 2.5 which may be conveniently carried about by a person, and is shown in its preferred form as comprising a casing 5 of flat formationv which isprovided in its interior with liquid and air chambers 6'and 7 disposed at'o'ppo-v site ends of the casing. The bottom of the casing has mounted thereon a closure plug 8 for the chamber 6, which plug may be removed for the purpose of pouring into said chamber asupply of liquid, such as perfume.

`Reciprocating.within the chamber 7 is a plunger 9 provided with the rod 1() which extends through the eXternally'screw threaded bushing 11 carried by the top of the casing. ,A nut 12 is secured to the outer end of the plunger rod 10 for rotary movement relative thereto and when the device is in /use saidA nut is threaded upon said bushing 11 to retain the plunger 9 in a depressed po- Y sition against .the tension of a spring 13 which vis interposed between the lower end of the plunger and a plate l14 carried upon the inner end of a plug 16 screwed in the bottom ofthe casing. This plug is provided with an air passage 17 communicating with ce the interior of thechamber 7 and normally 1928. Serial No. 284,836.

closed by a ball-valve 18. However, when the nut 12 is unscrewed from the bushing` 11 the spring 13 forces the plunger 9 outwardly, thereby creating a suction which draws air into the chamber below said plunger. Upon a depression' of thel rod 10 the valve 18 closes and the air in the chamber 7 is forced through the outlet pipe 19 and into the main pipe 20 joined to the pipe 19 through the coupling 21 carried by the lower end of the chamber 6. Adjacent the upper end of the pipe 20 the same is provided with a branch 22 communicating with the interior` of the chamber 6 above the level of the liquid therein.v The air entering the chamber 6 through the branch 22 creates a pressure above the liquid which forces the same upwardly through a feed pipe 23, the upper end of which is supported in the head 24 and the lower end of which terminates short of the filling plug 8. From the feedpipe 23 the liquid will enter the atomizing chamber 25 formed in the head 24 and will there be atomized in the manner to presently appear.

f The upper end of the pipe 20 is connected through a coupling 26 mounted in the top of the casing to one end of an inner' atomizing nozzle 27 projecting across the chamber 25 and into the screw threaded opening 28 of said chamber. Said opening is closed by an outer nozzle 29 having a discharge duct 30 therein, said nozzle being adapted to be' adjusted in the opening for a purpose which will presently appear. Carried in an inner enlarged recess 31 of the nozzle 29 is a springpressed valve 32 which, when the nozzle 29 is screwed inwardly to its greatest extent will close the outlet of the nozzle 27 and at the same time close the inner end of the duct 30, thereby preventing leakage of the liquid'v from the atomizer when the same is not in use. When the nozzle 29 is adjusted to the position shown in Figure 4, the spring of the valve 32 moves the latter to an inter- 95 mediate position.- Thus when air pressure is created in the nozzle 27 said air passing from the pipe 20 and through the coupling 26, the liquid entering the chamber 25, also by reason of said pressure, will be atomized 100 at the outlet end of the nozzle 27 and forced past the valve 32 and through the duct 30, there being suiicient space between said valve and the wall of the recess 31 to permit of the passage of said atomized liquid.

Vhat is claimed is:

1. An atomizer including a casing, liquid and air chambers in said casing, means to establish communication between said charnbers, means in said air chamber for transmitting air pressure therefrom to said llquld chamber to force the liquid therefrom, an atomizing chamber into which said liquid is discharged,` an atomizing nozzle in the latter chamber communicating withsaid air chambers to receive part of the pressure therefrom to atomize the liquid in said atomizing chamber, a discharge nozzle through which the atomized liquid Hows, and a springpressed valve carried by said discharge nozzle for closing the outlet end of said atomizing nozzle.

2. An atomizer including a casing, liquid and air chambers in said casing, means to establish communication between said chambers, means in said air chamber for transmitting air .pressure therefrom to said liquid chamber to force the liquid therefrom, an atomizing chamber into which said liquid is discharged, an atomizing nozzle in the latter chamber communicating with said air chamber to receive part of the pressure therefrom to atoinize the liquid in said atomizing chamber, a discharge nozzle having a duct therein and adj ustably carried by said atomizing chamber for movementtoward and away from said atomilzing nozzle, and a valve supported in said discharge nozzle for closing said duct and atomizing nozzle when said discharge nozzle is moved toward said atomizing nozzle.

3. An atomizer including a casing, liquid and air chambers in said casing, a main air supply pipe disposed between said chambers and communicating therewith, means in said air chamber for creating air pressure which is adapted to pass from said chamber vinto the liquid chamber through said air pipe, an atomizing chamber in communication with said liquid chamber and also with said air pipe, au inner nozzlein saidatomizing chamber forl receiving air "pressure fromisaid vair pipe, afeed pipe in lsaid `liquid chamber through which liquidis `forced into the.

atomizing chamber by the .pressureV entering said liquid chamber, a discharge nozzlehavv' 7 ing a duct therein and adjustably carried by said atomizing chamber for movement toward and away from said inner nozzle, and a valve supported in said discharge nozzle for closing said duct and inner nozzle when said discharge nozzle is moved toward said inner nozzle. 1
